Mongolian beef stir fry is a great all in one dinner that even my pickiest eaters love…serve it over steamed rice.
Here’s a bit of the How-To in photos. You can find the full recipe below.
To start, slice the flank steak against the grain into thin slices (about 1/4 inch thick.) Start near the top and cut down sideways for wider pieces of meat.
Pour the cornstarch into a bowl and lightly dredge the meat on both sides. Let the meat sit for 10-15 minutes to soak up the cornstarch.
Have the vegetables sliced thin and ready to cook.
Now you can start to fry the beef in the oil. Only cooking a few pieces at a time as to not over brown, or lower the temp of the oil.
At the very end, you will add the vegetables, cooked beef and sauce all together.
